Data transfer is a mess afaik, big reason I tend to buy my cables in different lengths, if it’s long I know it’s for charging, short it’s for data. Some manufacturers do mark the cable ends with their capabilities (ugreen for sure does this, just checked my power ones are marked 240w and my data a marked 10Gbps), my stuff is mostly older though so I don’t have a bunch of different data speeds to worry about.

I’m with you though, I’ll take it over a bunch of different proprietary cables.
